When the buffer plate 4 is moved by force, the slide 742 pushes the first reset spring 743, which can also dilute part of the force and keep the buffer plate 4 balanced against the outside of the inner box 2. A slide rod 744 is installed in the fixed seat 741, and the slide 742 moves on the slide rod 744, so that the deformation of the first reset spring 743 is stable and there is no deviation. By setting a guide block 745 to slide in the guide groove 746, the slide 742 can move smoothly, which is conducive to the stable movement of the buffer plate 4 under force.

[0026] refer to Figure 4-5The snap-fit ​​assembly 10 includes a slider 103, which is slidably connected inside the limiting frame 9. A second return spring 104 is fixedly connected to one end of the slider 103, and one end of the second return spring 104 is fixedly connected to the inside of the limiting frame 9.

Locking holes 101 are provided on both sides of the handle 8, and the locking block 102 is movably connected to the locking holes 101. The cross-section of the locking block 102 is an arc-shaped structure. By setting the snap-fit... When the inner box 2 does not need to be moved, the upper locking hole 101 of the handle 8 is connected to the locking block 102 in the limiting frame 9. The locking block 102 is fixed to the locking hole 101 by the second return spring 104, so that the handle 8 does not move easily. When the inner box 2 needs to be moved, the handle 8 is moved upward, and the lower locking hole 101 of the handle 8 is connected to the locking block 102 in the limiting frame 9. The locking block 102 is fixed to the locking hole 101 by the second return spring 104, making it convenient for the experimenter to move the inner box 2 outward and take it out.

[0027] refer to Figure 1 Both ends of the lid 11 are fixedly connected to connecting blocks 12, and both ends of the outer box 1 are fixedly connected to connecting seats 13. A locking rod 14 is threadedly connected to one side of the connecting seat 13, and one side of the locking rod 14 is threadedly connected to the connecting block 12. Both sides of the lower end of the lid 11 are fixedly connected to inserts 15, and both sides of the upper end of the outer box 1 are provided with slots 16. The inserts 15 and slots 16 are movably connected.

The inserts 15 and slots 16 are provided to facilitate the combination and connection of the lid 11 and the outer box 1.

[0028] Operating principle and advantages: The culture is placed into the inner box 2, which is then placed into the outer box 1. At this time, the two buffer plates 4 and the two air cushions 3 clamp and fix the inner box 2. When the culture box is subjected to vibration, the outer box 1 protects the inner box 2. After the buffer plate 4 is subjected to force, it pushes the fixing block 71, which in turn pushes the balance bar 72. The balance bar 72 pushes the moving block 73, causing the slide 742 to slide on the fixing seat 741. The slide 742 slides stably on the sliding rod 744, preventing deviation. The slide 742 pushes the internal first return spring 743, which can absorb the vibration. The impact force is reduced, keeping the buffer plate 4 balanced. At the same time, the shock-absorbing spring 5 and the damper 6 are pushed, effectively reducing the transmission of impact force from external impact to the inner box 2, reducing the risk of damage to the internal culture, protecting the integrity and stability of the sample, and promoting the growth of the culture. When it is necessary to remove the inner box 2, the handle 8 is moved upward. The lower side of the handle 8 is connected to the locking block 102 in the limiting frame 9. The locking block 102 is fixed to the locking hole 101 by the second return spring 104. At this time, the handle 8 extends out of the inner box 2, making it convenient for the experimenter to move the inner box 2 outward and remove it.
